VPS control module EMC modeling and evaluation

The present paper is the result of studies, experiments, modeling and simulation regarding electromagnetic compatibility (EMC) of an electronic module able to control and vary the power requirements of a Vapor Phase Soldering (VPS) machine in order to obtain the desired thermal profile. The original electronic solution has been designed to obtain very low radiated electromagnetic emission during operation by switching the power device when the AC main is zero-crossing. Electromagnetic compatibility (EMC) performance and field effects have been analyzed using 3D EM simulation software, REMCOM XFdtd by considering the VPS process control module the source of radiations. EMC evaluations of the electronic module regarding conducted and radiated emissions have been done in laboratory in order to validate the modeling and simulations results. In order to complete the design for excellence (DFX) activities in case of new products development processes the authors intend to develop a design methodology which will include modeling and EM simulation for optimum electromagnetic compatibility within the Vapor Phase Soldering system.
